Rohde & Schwarz R&S®NGM200 Power Supply Series 9
The battery simulation software includes data sets of common battery
types that can be easily modified.
Using the two-channel R&S®NGM202, battery simulation can be used
simultaneously on both channels.
Battery models
Real batteries show different characteristics depending on
the type of battery and its charging condition. Capacity,
open circuit voltage (Voc) and equivalent series resistance
(ESR) are important battery characteristics that depend
on its state of charge (SoC). The optional R&S®NGM-K106
functionality allows users to simulate the behavior of
batteries under different charging conditions, e.g. when
powering a DUT.
To define a battery model, the data of the battery can be
entered easily using the integrated battery model editor.
Data sets for the common battery types Pb, LiIon, NiCd
and NiMH are available as preconfigured files. These can
be easily modified according to the needs of a specific
application. Additional battery model data sets can
be loaded from a USB device and stored on the
R&S®NGM200 power supplies.
Battery simulation
In particular, when battery-operated devices have to be
optimized for lifecycle, the discharging behavior of the
used battery type needs to be considered. The battery
simulator function of the R&S®NGM200 makes it possible
to simulate the real battery output performance. Testing
can be based on a selected battery model, while battery
capacity, SoC and Voc can be set to any state to test the
device under specific circumstances.
The charging behavior of a battery can also be simulated.
This is particularly important when designing battery
chargers. In this application, the R&S®NGM200 power
supply is used in sink mode.
Both cases provide dynamic simulation, meaning Voc,
ESR and SoC change according to charging/discharging
conditions like a real battery. The state of charge is shown
graphically; all other values are displayed numerically.
Battery simulation: the main parameters to characterize a battery’s
condition are summarized in one display.
